What To Look For In Fly Sprays

Fly spray comes in either water or oil-based formulas. Both types work well to repel flies, though some people have preferences of one over the other. For horse fly spray that actually works, look for reliable brands such as Farnam, Absorbine, and Pyranha.

Oil-based fly sprays generally work efficiently and quickly to keep flies away. When applied, the bugs can suffocate or in some cases drown in the oil. However, the disadvantage of oil-based fly spray is that it attracts dust, so it is hard to keep your horse clean.

Water-based fly spray does not attract dust, so it is easier to keep your horses clean. It is a great option to use if you show, as you don’t have to worry about dust accumulating on your clean horse. Certain water-based formulas are even all-weatherproof, which is ideal for horses that live outside.

What Is The Best Way To Use Fly Spray?

Fly spray should be applied all across a horse’s body. However, you should be careful to avoid getting it in the eyes, nose, or mouth. For best results, apply fly spray to a clean, dry horse before turnout, exercising, or as needed.

Depending on the type, you will need to reapply daily or every 7-14 days. Always be sure to read the instructions on the bottle before spraying it on your horse.

Prerequisites To Using Fly Spray On Your Horse

When using fly spray on your horse, only apply it to a small patch of skin first. Wait at least 20 minutes to see if your horse has an adverse reaction before using it on your horse’s entire body. If the horse spray for flies causes irritation in your horse, do not use it.
